. Goodwill and Goodwill Impairment
 
The Company’s policy is to assess goodwill for impairment at the reporting unit level on an annual basis or between annual assessments if a triggering event occurs or circumstances change that would more likely than
not
reduce the fair value of a reporting unit below its carrying amount.  Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value.  
 
As of
March 31, 2018,
the Company’s market capitalization was above book value and there was
no
triggering event that required the Company to assess goodwill for impairment as of an interim date.
